Hi there,

I'm wondering if there's a way to identify the frequency spectre is sweeping when I run a .ac analysis. Just as I can get the $temperature in .dc sweep, how could I get the frequency ?

There's nothing officially in the Verilog-AMS language to get the frequency -- partly to avoid people trying to make a model that depends on frequency:

V(out) <+ I(out) * $frequency * cap; // nonsense

I don't know if Spectre provides a way to print the frequency.
